Fleck 3150 Automatic Systems 2
Fleck 3150/1800 2" Commercial Systems
Please Note: The piping from the brine tank to the mineral tank is NOT provided with these systems.
One-inch connections are provided at the 1800 brine valve and brine tank. Local plumbing codes and
flow rates dictate the type of piping used between the brine tank and mineral tank. Also note, the
maximum flow rate for a 2350 safety valve is 10 gallons per minute. The recommended refill rate for a
900,000 grain system is 10 gallons per minute. A consideration should be made as to the type or number of air check(s)/safety(s) installed in the brine tank with these systems.
